Description

Technical Field

[0001] This utility model belongs to the field of door stop technology and relates to a safety door stop. Background Technology

[0002] A door stop is a device that positions a door after it has been opened to prevent it from closing due to wind or contact with the door leaf.

[0003] The applicant previously developed a concealed door stop with authorization announcement number CN218206271U, which includes a base. The base is connected to a positioning post and a door stop post that can move up and down relative to the base. The positioning post always tends to move upward. The base is provided with a swing rod. The middle part of the swing rod is hinged to the base. One end of the swing rod is raised and located below the positioning post. The other end of the swing rod is located below the door stop post. When the door drives the positioning post to move downward, it can drive one end of the swing rod to move downward, and cause the other end of the swing rod to drive the upper end of the door stop post to extend out of the base.

[0004] The aforementioned door stop is compact and aesthetically pleasing, but it still has some shortcomings: After the door is closed, the door stop assembly is exposed on the indoor floor. When users are moving around indoors, they often accidentally step on the area of ​​the door stop and the positioning post. Because the two are linked by the swing arm, the door stop will extend upwards when the positioning post is pressed down, meaning that the two cannot be hidden in the seat at the same time. Indoor users often only wear slippers or go barefoot. At this time, the upper part of the door stop will exert greater pressure on the user's feet, causing pain or even injury. Excessive downward pressure on the door stop can also easily deform and damage the swing arm and other linkage mechanisms, ultimately causing the door stop to malfunction. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a safety door stop. The technical problem this utility model aims to solve is that existing door stop structures pose safety hazards.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A safety door stop includes a mounting base. A positioning post and a door stop post are connected within the mounting base and are movable vertically relative to the mounting base. The upper ends of both the door stop post and the positioning post extend beyond the upper side of the mounting base. A reset element is provided between the positioning post and the mounting base to ensure the positioning post always has an upward moving tendency. The door stop post is characterized by being further characterized by a reset element provided between the door stop post and the mounting base to ensure the door stop post always has an upward moving tendency. The positioning post and the door stop post can move downwards until the upper ends of both the positioning post and the door stop post are simultaneously flush with the upper side of the mounting base.

[0008] The mounting base is used for installation on the ground or floor. The positioning post and the door stop post are connected within the mounting base and can move up and down independently. The upper end of the positioning post engages with the positioning groove on the bottom surface of the door for positioning. The door stop post abuts against the side of the door when it is fully open, creating a limit and ensuring precise alignment between the door and the positioning post. Under the action of the reset component, the positioning post maintains an upward tendency, ensuring a proper positioning against the door. Simultaneously, when the door is closed, the positioning post smoothly resets to prepare for the next positioning operation. The reset component can be an existing ordinary compression spring, a tower spring, a tension spring, a soft elastic block, or a repulsive magnet, etc. By connecting the door stop post and the mounting base... A second reset element is installed between the seats. The second reset element can be an existing ordinary compression spring, tower spring, tension spring, soft elastic block, or repulsive magnet. It allows both the positioning post and the door stop post to move downwards to their upper ends and be flush with the upper side of the mounting seat. In this way, when the door stop post is in normal condition, its upper end remains extended due to the action of the second reset element. When the user accidentally steps on the door stop post and the positioning post, the door stop post and the positioning post can independently collapse downwards under pressure, avoiding rigid interference with the user's foot, protecting the user's foot from injury, and improving safety. After the user moves their foot away, the door stop post and the positioning post can automatically reset to prepare for subsequent door stop positioning.

[0009] In the aforementioned safety door stop, the bottom of the door stop post has an axially positioned positioning hole. The second reset element is a compression spring positioned vertically, with its upper end located within the positioning hole and its lower end abutting against the mounting base. This design allows for a sufficiently large length of the second reset element, minimizing its stiffness coefficient and reducing the reset force generated when the door stop post is stepped on, thereby reducing pressure on the user's foot and ensuring safety.

[0010] In the aforementioned safety door stop, the upper side of the mounting base has a vertically arranged guide hole. The door stop post is radially positioned within the guide hole and can slide up and down along the inner wall of the guide hole. The length of the door stop post within the guide hole is greater than the length of the door stop post extending out of the guide hole. The guide hole provides radial positioning and movement guidance for the door stop post, ensuring smooth movement. Furthermore, allowing the door stop post to extend into the guide hole to be larger also helps ensure that the door stop post remains stable when subjected to impact.

[0011] In the aforementioned safety door stop, the radial dimension of the positioning post is larger than that of the door stop post. Because the positioning post needs to be positioned against the top of the door, the force exerted by the reset component on the pair of positioning posts is relatively large. This allows for a larger contact area when the user steps on the positioning post, preventing excessive pressure on the feet and thus avoiding safety risks.

[0012] In the aforementioned safety door stop, the mounting base is disc-shaped, with a protrusion in the center of its lower side. The lower ends of the positioning post and the door stop post are inserted into the protrusion. The upper side of the mounting base has at least two vertically arranged mounting through holes, which are located on both sides of the protrusion. When installed on a floor, mounting holes adapted to the protrusion can be made in the floor, and the protrusion can be inserted into these holes. The mounting base around the protrusion can then rest on the floor surface. Assembly of the mounting base can be achieved by adding connectors such as screws through the mounting through holes. Installation is convenient, and the protrusion utilizes the space beneath the floor, reducing the size of the entire door stop protruding from the floor surface and significantly lowering the risk of tripping, thus enhancing safety.

[0013] In the aforementioned safety door stop, a decorative cover is fitted onto the mounting base, which covers both mounting through holes from top to bottom. This decorative cover provides a protective layer to the surface of the mounting base, reducing the risk of external scratches. Furthermore, it conceals the connectors within the mounting through holes, preventing corrosion and loosening, and also enhances the aesthetics.

[0014] As an alternative, the upper end of the positioning post is tilted away from the side of the door stop post. This way, when the door opens and contacts the positioning post, the force of the door is more fully applied to the positioning post, pushing it downwards and reducing the impact of the door on the positioning post, thus ensuring operational stability.

[0015] In the aforementioned safety door stop, the positioning post includes a cylindrical lifting sleeve with a sealed top and a columnar positioning seat. The top of the lifting sleeve is rounded, and the upper end of the positioning seat is screwed into the lower end of the lifting sleeve. Thus, the lifting sleeve can change the length of the entire positioning post by rotating relative to the positioning seat, thereby facilitating changes in the height position of the upper end of the positioning post to accommodate different door heights during installation.

[0016] As another embodiment, the positioning post includes a cylindrical lifting sleeve and a columnar positioning seat. The upper end of the lifting sleeve is constricted, and a ball bearing that partially extends out of the upper end of the lifting sleeve is provided inside the lifting sleeve. The upper end of the positioning seat is screwed into the lower end of the lifting sleeve. The lifting sleeve also includes a reset element three that acts between the bottom of the ball bearing and the positioning seat. In this way, the length of the entire positioning post can be changed by rotating the lifting sleeve relative to the positioning seat to meet the installation requirements of different door heights. At the same time, the ball bearing can extend out of the upper end of the lifting sleeve under the action of the reset element three, and then roll and rub against the bottom surface of the door, thereby reducing frictional resistance. Moreover, when subjected to greater force, the ball bearing can also adaptively and independently collapse downwards to avoid damage to the components.

[0017] As another embodiment, the mounting base is in the shape of a horizontal plate, and the gate post includes a vertically arranged blocking post and a positioning sleeve. The lower end of the blocking post is slidably connected to the positioning sleeve and can slide up and down relative to the positioning sleeve. The lower end of the positioning sleeve is slidably connected to the mounting base and can slide up and down relative to the mounting base. The upper end of the reset member acts on the bottom of the blocking post. The vertical height of the blocking post and the vertical height of the positioning sleeve are both smaller than the vertical thickness of the mounting base. In this way, when in operation, the blocking post extends from the upper end of the positioning sleeve under the action of the reset component, and at the same time, it pulls the positioning sleeve to extend from the upper side of the mounting base. This ensures that the overall height of the blocking post extending from the mounting base meets the blocking requirements. When the blocking post is stepped on, the blocking post can retract downward into the positioning sleeve, and the positioning sleeve can be hidden inside the mounting base. That is, while meeting the blocking requirements, the final retracted height of the blocking post is smaller, which greatly reduces the thickness requirement of the mounting base. Therefore, when assembled onto the floor, it does not need to occupy the space under the floor, avoiding the need to drill holes in the floor. This makes installation convenient and more acceptable to users.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] When the door is closed, if a user accidentally steps on the door stop and positioning post, the door stop and positioning post can collapse downwards independently under pressure, avoiding rigid interference with the user's foot and protecting the user's foot from injury, thus providing superior safety.
